登錄后如何使Linux從Spring Boot啟動？

Question

在Linux登錄失敗之后，我嘗試從spring開始啟動，有人可以告訴我我做錯了什么嗎？

我有兩個問題..

我可以僅通過調用sudo用戶來運行該應用程序，如果沒有發生以下錯誤

向我解釋為什么會發生此錯誤..如何使應用程序在Linux上的用戶登錄后運行，並指出該登錄是在沒有sudo權限的情況下自動發生的，那么jar應該以755權限運行嗎？

thank you advanced.

Answer 1

應該簡單明了。我相信您使用的是端口80，而不是8080：

低於1024的端口是特權端口，因此需要sudo用戶

請參閱文件：

http://www.w3.org/Daemon/User/Installation/PrivilegedPorts.html

通過類似於-Dserver.port = 8080的運行VM參數傳遞服務器端口，或者搜索application.properties並在其中指定server.port = 8080。

以上應該可以正常工作。

希望這可以幫助。
